The circumference of a circle is given by:
[tex]C=2\pi r[/tex]
Where r is radius of the circle .
Now the relation between radius and diameter is given as:
Radius * 2 =Diameter
So replacing 2r by "d" in the equation of circumference,
[tex]C=\pi d[/tex]
We are given value of circumference as 361/pi
Plugging this value in the formula for circumference,
[tex]\frac{361}{\pi }=\pi d[/tex]
Answer: Diameter is given by:
[tex]d=\frac{361}{\pi ^{2} }[/tex]
